If the closest planet in the Solar System to the Sun was able to support life (as we understand it) this is what our homeworld would look like to them — a double planetary system (or more likely as perceived, a binary star) — from even our closest approach to them, 48 million miles away. So according to Mercurians, we are not a pale blue dot but instead a nearby, very bright, double-dotted neighbor. Ray Villard writes on Discovery News:
I never cease to be humbled and amazed when I see our Planet Earth reduced to a pinpoint when photographed from elsewhere in the solar system. So far, our planet-roaming spacecraft have taken tourist snapshots of Earth as seen from Mars, Saturn, and beyond Pluto’s obit.
But this latest view from NASA’s MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging) spacecraft is a jaw-dropper. For the first time we see Earth — in astronomical parlance — as a fully illuminated superior planet 114 million mile outward from Mercury. Earth really looks like a double star because the moon is snuggled up next to it.
If in some parallel universe Mercury had intelligent life, its science equivalent of Galileo would have cataloged Earth as a “double planet,” because our moon is so comparatively large next to Earth.
